SELF-CLOSING VALVE.

Specification of Letters Patent.

Paton ted Feb, 3, 1916.

Application filed July 1! 1915. Serial No. 29,060.

To on whom it may concern:

Be it known that I, Cnnnnns ILIhEsnLnn, V

a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Self-Closing Valve, of which the folfurther consists 0 such a. valve in which a screen-atthe-receiving end of/the duct of the casing'is protected from injury.

It further consists of such a, valve in which the handle is locked-when the valveplug is open I It. further consistsof other novel features of construction," all as" will, be hereinafter fullysetforth,

The annexed drawings and the following description set'iforth. in detail one mechani- 1 cal .-form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may bejised.

\ In said. annexed drawlngsfFigure 1 represents an axial section of the valve or cook embodying my'invention. Fig. 2 representsatransverse section on the line w w, Fig. 1.

Fig. 3 represents an axial section of the strainer and its protective shell. Fig. t

represents an end-view of such shell. I

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, the reference numerall indicates a valve casinghaving a longitudinal bore, ,2, and an exteriorly threaded neck, 3, at one end of the casing and a cylindrical recess, 4, vat the 'other end closure.

said chamber and has diametrically oppoof the bore having a beveled shoulder, 5, and an interiorscrew-thread, 6, in the outer portion of the recess. A transverse cylindrical chamber or seat, 7, extendsthrougli the casing and intersects the longitudinal bore, having one end partly closed and formed with a central opening, 8, in such A tubular lining, 9,'is fitted in site ports, 10, which register with'the ends o-f'the longitudinal bore. A plug, 11, fits to slide within the chamber and has a 1'8.

cess, 12-,in its end int'oiiwhich one endijof coiled spring, {10, fits while-,thegbther end of the spring abuts against theinner facev I of the annular closure, 13, lof. thev chamber.

A transverse bore, 14, is formed through the plug and is of the same diameteras the longitudinal bore and registers with th'e I ports in the lining whenthe valve is pushed."

the valve-plug has a transverse groove, 15, formed withflanges, 16, on the sidesof the groove and having arcuate concaveedgeainward in its chamber. 'l he outerend of 20. -Ears, 17, project from the end of the casing and an eccentric disk, 18', is pivoted to oscillate between such ears upon. a bolt,

19, passing through theears and eccentrically through thefdiskj.

diametrically opposite the portiom'contactwith the valve plug, when the parts I are in the position seenin apparentthat when said handle and operat mg disk are rotated in the direction of the Fig. 1, it being arrow'seen in Fig. 1, or from left to right, said fiatedge will engage the bottom of the groove in the top of the valve plug, the latter being pressed outwardly by the spring 40, whereby said disk and plug will be effectively locked and prevented from accidental movement unless the handle 21 is manually or otherwise ope rated.

' A cylindrical shell, 23, fits in the cylindrical recess of the valve-casing and is lo'n-' gitudinally movable in said recess, and an annular plug or bushing, 24,'has a threaded neck, 25, which is screwed in the screw threaded recess 6 to retain the shell. The

shell has a cylindrical wall, 26, and a pref erably integral head, 27, .formed-with an annular series of openings, 28, and the interior of the wall has an annular shoulder, 0, at the inner end of said wall. nated metallic cap, 31, of-woven wire'or perforated sheet-metal fits with its flange in the wall of the shell andrbears against; the shoulder 30, and an annular wall, 32, of-

A foramia cap, 41, is fitted into the flange of the foraminated cap arid has an annular series (if openings 33 in its head and secures the foraminatedcap in the wallgof the-shell. The annular plug or bushing 2fi= has its screw-threaded inner portion 25 screwed into the outer threaded bore, 6, to lock the shell in its recess and has an enlargement, 36, adapted to be engaged by a toolfor turning it, and the innerbore, 37, of such nut is a*.re\v-tl1readed to have hose secured in it.

In practice, the. air-hose'is "connected to the bushing 24, and the percussion tool or other device to be driven is Connected to the threaded neck. \Vhen the handle iS tilted parallel to the bore of the valve; and with the short radius portion of the eccenend of the airtrio hearing against the .end'of the -"valve plug, the spring 21- movesfth'e' :faucet-plug upward and thevalve 'i sfelose handle is turned to bringthe' flat'portion of the edge of "the eccentrio' 'disk'torbear against the plug to press it inward' against the spring, the longitudinaljhore oflthe casing and the transverse horelinthe plug'are brought toregiste'r witheacli'hther and the g the faucetgand hose;, the

lVhile the strum we is especially intended for use with jackhammers and drills and similarinq'iiements. it is evident that the valve may be employed in hoseor similar "conduits for cleaning the'tluid passing through it from dirt, sand or other impm-itics.
